..04). Our timely study shows patterns of occurrence of childhood cancer that differ with respect to ethnic group. Differences are particularly apparent in the excess of AML and incidence peak in 5-9 year olds in south Asian children...

UK case control study of brain tumours in children, teenagers and young adults: a pilot study

..Population mixing, as a possible proxy for infectious exposure, has been well researched for childhood malignancies. We aimed to investigate effects of population mixing in this older age group using an English national cancer dataset...

..We specifically tested the aetiological hypothesis that a factor influencing geographical or temporal heterogeneity of childhood central nervous system (CNS) tumour incidence was related to exposure to a transient environmental agent...

..To investigate the feasibility of obtaining signed consent for submission of patient identifiable data to a national clinical audit database and to identify factors influencing the consent process and its success...

..These results may have a biological explanation with raised immunosurveillance in atopic individuals protecting against the development of brain tumours. Alternative explanations might include bias, reverse causality or confounding...

Cancer incidence among the south Asian and non-south Asian population under 30 years of age in Yorkshire, UK

..The purpose of this work was to investigate the incidence rate for admission and mortality of children receiving paediatric intensive care in relation to socioeconomic status and ethnicity in England and Wales...

Trends in the incidence of childhood diabetes in south Asians and other children in Bradford, UK

..Spatial variation is examined in some detail. At county and district levels there is little heterogeneity in the distribution of cases. However, at the electoral ward level there were real differences for the younger age group (0-34)...

..Other children in the home had the greatest association with infectious class membership. Latent class analysis provided a flexible method of investigating the relationship between multiple symptoms and demographic and lifestyle factors...

Treatment and survival patterns for germ cell tumors among 13- to 24-year olds in Yorkshire, UK

..However, between disciplines protocols define different assessment and management in GCT. We aimed to document changes in incidence, treatment, and survival since 1990, to record the baseline to which future trends can be compared...

Rising rates of all types of diabetes in south Asian and non-south Asian children and young people aged 0-29 years in West Yorkshire, U.K., 1991-2006

..We aimed to describe and contrast the epidemiology of haematological malignancies among 0-14 and 15-24-year-olds in northern England from 1990 to 2002 and compare clinical trial entry by age group...

..7) and duration (by a factor of 2.8). These results suggest that self-reported mobile phone use may not fully represent patterns of actual use. This has implications for calculating exposures from questionnaire data...

Socioeconomic status and risk of adenocarcinoma of the oesophagus and cancer of the gastric cardia in Scotland

..In contrast to other cancers of the oesophagus and stomach, which showed a clear relationship with socioeconomic status, no trend was evident for oesophageal adenocarcinoma or gastric cardia cancer during 1987-1996...

..Health professionals need to be continually updated and made aware of the legislation and confidentiality requirements for health service research involving the collection of patient-identifiable details...

Childhood cancer and power lines: results do not support causal role for electromagnetic fields

..The study showed an inverse association of glioma risk with allergic disease. Possible reasons for the association, as well as potential immunological aetiology, include confounding, bias and reverse causality...
